Forum: movies Subject: Re: why are thumbnails not created sometimes?

yes, thanks - i actually already managed to do that...

i was just mentioning this here, since i plan to upload all my future works as mpeg4/h.264 encoded files and the d.i.y. thumbnail creation can be a bit time consuming.

since you don't rule out that the deriver does not understand the h.264 encoding of my movie, here is what i did:

i exported from final cut (using the then latest quicktime 7.0.3) and encoded the .mp4 with an image size of 720 x 576, 25fps, 896 kbits/sec for picture - best quality/multi-pass - and 128 kbits/sec for sound using the aac codec. quicktime also said that "the file conforms to mp4 file format specification". so this looked o.k. to me, but obviously i can't rule out some strange or unknown quicktime related bug.

if there are any limitations to what the deriver can handle (kbits/sec etc.) then it would be good to know... (maybe interesting in that context: the actual file size of "vincent" is 332 mb, but the movie's site now says it's 348 mb.)

thanks,

valentin (indiworks)
